Complete the balanced equation for the precipitation reaction of magnesium chloride with sodium hydroxide by writing the correct number in front of NaOH.
MgCl2(aq)+.....NaOH(aq)→Mg(OH)2(s)+2NaCl(aq) \text{MgCl}_2\text{(aq)} + \text{.....NaOH(aq)} \rightarrow \text{Mg(OH)}_2\text{(s)} + 2\text{NaCl(aq)} MgCl2(aq)+.....NaOH(aq)→Mg(OH)2(s)+2NaCl(aq)
